The picture to the left is from February this year. Today, I saw petrol (gas, diesel fuel) for 1.419 pounds/liter. That works out to 6.45 pounds per UK gallon or 5.36 pounds per US gallon (yep, they are different). That works out to $8.62 per US gallon.
I think this is some of the most expensive gas I’ve ever seen.
